SPECIFICATION forming part of Letters Patent No. 293,266, dated'February 12, 1884.

Application filed August 7, 1883. (No model.)

To all whom it mag concern.-

Be it known that I, THOMAS MnIKLn, of Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful Improvement in Cultivators, of which the following is a specification.

My invention relatesto the joints and supporting-spring foot of the cultivator, illustrated in the annexed drawings, which make a part of this specification, in whieh Figure 1 is a side elevation, showing one of the sections of a straddle-row cultivator. Fig. 2 is a top view of the entire cultivator. Fig. 3 is a vertical section through the joint which allows vertical play to the beams. Fig, 4 is side pieces of the said joint. Fig. 5 is an elevation showing the outside of one of the plates of the joint, with the drag-bar attached. Fig. 6 is an edge view of the piece shown in Fig. 4. Fig. 7 is an elevation of the same piece shown in Fig. 5, without the drag-bar. Fig. 8 is an elevation of the middle piece of the joint; and Fig. 9 is a vertical section of the joint, showing the mode of attaching the arch.

The same letters are employed in all the figures in the designation of identical parts.

The beam, drag-bars, yoke, and plows being familiar need not be described in detail.

The drag-bars A are connected to the beam B by a compound joint formed of three pieces. The middle piece, 0, is attached to the plates E E, which are fastened to the beam B above and below, and project in rear of the beam far enough to receive the piece 0 between them, and also the stern D of the arched yoke D, which connects the beams and permits them to play freely and independently forward and back, swiveling upon the stem D, and also permitting the beams to play freely sidewise, turning upon the stems D as pivots. The piece 0 is formed with a ring, 0, projecting rearward, and is shown in Fig. 8. It is constructed with an annular flange, (J and a re ces's, O to receive and restrain the motions of a projection on the pieces F F, which are constructed as follows: The external portion has a recess to receive the drag-bar, as shown in Figs. '5, 6 and 7. The hub F fits the inside of the recess .0, Fig.8, and hasa projecting lug, F3 which is received into the correspond ing recess C, but is not as wide as'the recess, I

so as to afford a limited vertical play to the dragbars. A still smaller hub, F fits into the hole 0*, and has a hole to receive the pin G, which passes through the plates F (which are made right and left) and through the hole 0, as well as through eyes in the forward ends of the drag-bars A. By this means a limited vertical oscillation is allowed to the drag-bar, and at the same time a limited horizontal oscillation, as well. as a limited play forward and back.

The bifurcated spring-foot H is hung on a bolt, I, which passes through the two drag bars, and has its arm II bent so as to form a double catch, by ,means of which the spring can be held in its downwardprojection, so as to support and suspend the shovels or plows above the ground 5 or, when lifted so as to free the drag-bars, the spring itself may be supported suspended upon the cross-bar K, so as not to interfere with the action of the plows. This spring-foot affords a convenient mode of supporting the plows when moving without working, and is itself supported when they are atwork.

hat I claim as my invention, and desire to secure by Letters Patent, is

1. In combination with the beam B and drag-bar A of a cultivator, a coupling eonsisting of the central piece, 0, pivoted to the rear end of the beam, and the side pieces, F F, attached to the front end of the drag-bar and pivoted to the piece C, said parts being constructed, respectively, and arranged to form a compound joint substantially as set forth.

2. In combination with the drag-bars and beams of a straddle-row cultivator, the archyoke D, having stems D, connecting the beams and turning in the beams to permit the fore and aft independent play of the plows, and said stems D also forming pivots on which the drag-bars swing from side to side, substantially as set forth.

3. In combination with the verticallyswinging drag-bars of a cultivator, the swinging bifurcated spring-foot H H, the elastic arm i In testimony whereof I affix my signature in H of which is curved, substantially as shown, presence of two Witnesses.

so as to perform the double function of supporting the spring-foot itself on the cross-bar THOS. MEIKLE. K of the drag-bars, or of supporting the drag- I bars on the spring-foot when the former are lVitnesses:

raised, so as to lift the shovels above the ground, GEO. T. MEGOWAN,

substantially as set forth. 'S. GUNTHER.
